September 2025 update: I have been making this recipe for Breakfast Casserole for years but I first shared it back in March of 2024. In this update, I freshened up the post, added some more details that will help you out and included more pictures. Please let me know what you think.
👩🍳What Makes This Breakfast Casserole Special
When you’ve got a crowd in the morning, make-ahead breakfasts are a lifesaver. A breakfast casserole comes together easily and feels like a full meal, especially if you serve it with something simple like pancakes or fruit on the side. Over time I’ve learned that the secret to a light, fluffy casserole is using heavy cream instead of milk and whisking the eggs until they’re airy. A stand mixer does the job perfectly.
This sausage breakfast casserole has layers of flavor and texture. The base is sweet potato slices that soften in the oven while the hot pork sausage adds a savory, slightly spicy note. Onions, peppers, carrots, and broccoli bring freshness and color, while the egg and cream mixture bakes into a custardy layer that holds everything together. A topping of cheddar melts into a golden, cheesy crust that makes each bite rich and satisfying.
It’s the kind of dish that works just as well for a Sunday morning before church as it does for a weeknight dinner when breakfast for dinner sounds like the best idea. You can keep it simple with sausage and cheese or change it up with different vegetables and seasonings. However you build it, the result is a hearty, homemade casserole that’s easy to slice and share.

🥣 Step-by-Step Guide to Making Breakfast Casserole
Preheat your oven to 350°F and butter a 9×13 casserole dish so your breakfast casserole doesn’t stick. In a large skillet, cook the hot pork sausage over medium-high heat, breaking it into crumbles as it browns. This step builds the savory base of the sausage breakfast casserole. Once the sausage is cooked through, stir in the onion, red bell pepper, and carrots. Let them sauté until tender and aromatic, which adds depth and sweetness to the cheesy breakfast bake.
In a large mixing bowl, whisk the eggs with the heavy cream, a pinch of salt, and freshly ground black pepper. Whisk until smooth and slightly frothy. This egg mixture is what makes the breakfast casserole light, fluffy, and custardy instead of dense.
Arrange thin slices of sweet potato across the bottom of the prepared baking dish. The sweet potatoes create a sturdy base layer with a touch of natural sweetness. Spread the sausage and vegetable mixture evenly over the potatoes, then scatter the broccoli florets on top for fresh flavor and extra nutrition. Slowly pour the egg and cream mixture over everything, letting it sink into the layers. Finish by sprinkling cheddar cheese across the top, which will bake into a golden, cheesy crust.
Bake the sausage breakfast casserole uncovered for 40 to 45 minutes, or until the center is set and the top is puffed and lightly browned. A toothpick inserted in the middle should come out clean. Let the cheesy breakfast bake rest for 5 to 10 minutes before slicing and serving. This short cooling time helps the layers set so the casserole cuts into neat squares.

FAQs
Can I use frozen vegetables instead of fresh?
Yes, frozen veggies work fine, but it’s best to thaw and pat them dry first. Too much water can make the casserole soggy.
Can I assemble this casserole ahead of time?
Yes, but for the best texture, whisk and pour the egg mixture right before baking. If you want to prep it the night before, keep the egg mixture separate in the fridge and pour it over the layers in the morning.
Serving Suggestions
This sausage breakfast casserole is hearty enough to stand on its own, but it pairs well with a few simple sides if you’re feeding a crowd. Fresh fruit like berries, melon, or citrus keeps the plate bright and balances the richness of the cheesy breakfast bake. A batch of pancakes or waffles on the side makes it feel like a full brunch spread without much extra work.
If you’re serving this casserole for a holiday or weekend gathering, add something savory on the side such as crispy bacon or breakfast potatoes. For a lighter touch, a green salad or roasted asparagus works surprisingly well with the fluffy eggs and sausage. And if you’re like me and love breakfast for dinner, try serving it with crusty bread and a small bowl of soup to round out the meal.
